iptables - unable to add a rule with any matching conditions [solved]

I can NOT add rules to iptables like:
# iptables -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
# iptables -A INPUT -p udp -j REJECT

I can add rules to iptables like:
# iptables -A INPUT -i lo -j ACCEPT

When I attempt to add rules with matching conditions, I receive the error, "iptables: No chain/target/match by that name."  I have tried adding a chain called INPUT, but get an error that it already exists (which is what I expect).  I'm not sure where to go from here, and for bonus points, this system is in a locked closet about 2 hours travel from where I am, so I need to be careful in not killing my own remote access while working on it.

Thanks in advance for any suggestions,

KD

I hate to say it (Oh man I hate to say it).  Rebooted system and now the commands work.
